4-Methoxy-anilinium bromide.

Project description:The title compound, C(7)H(10)NO(+)·Br(-), consists of almost planar 4-methoxy-anilinium cations, wherein the O atom lies 0.049?(3)?Å out of the plane formed by the non-H atoms, and a Br(-) anion. Strong N-H?Br and N-H?(Br,Br) hydrogen bonding contributes to the stability of the crystal structure and links the cations and anions into a three-dimensional network.

2,4-Dimethyl-anilinium chloride.

Project description:In the crystal structure of the title compound, C(8)H(12)N(+)·Cl(-), all H atoms bonded to the ammonium N atom are hydrogen bonded to the chloride ions, with N?Cl distances in the range 3.080?(2)-3.136?(2)?Å, resulting in 16-membered macrocyclic rings involving four formula units of the title compound.

2-Acetyl-anilinium chloride.

Project description:The cation of the title salt, C(8)H(10)NO(+)·Cl(-), is essentially planar [C-C-C-C torsion angle = 4.6 (2)°], the conformation being stabilized by an intra-molecular N-H⋯O hydrogen bond. In the crystal, centrosymmetric aggregates are formed via N-H⋯Cl hydrogen bonds. These dimeric aggregates are sustained in the crystal packing by a combination of C-H⋯Cl, C-H⋯O and C-O⋯π [O⋯ring centroid(benzene ring) = 3.1871 (13) and 3.3787 (13) Å] inter-actions.

3-Cyano-anilinium chloride.

Project description:In the title salt, C(7)H(7)N(2) (+)·Cl(-), all non-H atoms of the cation are essentially coplanar (r.m.s. deviation = 0.005 Å). In the crystal structure, the organic cations and chloride ions are linked to form a two-dimensional network parallel to the (001) plane by N-H⋯Cl hydrogen bonds.

2,6-Diisopropyl-anilinium chloride.

Project description:The title compound, C(12)H(20)N(+)·Cl(-), crystallizes with the chloride anions situated on twofold axes, while the cation is on a general position. All conventional hydrogen-bond donors and acceptors are utilized, forming a hydrogen-bonded ladder motif along the c axis. Investigation of the torsion angles between aromatic systems and isopropyl groups reveals unusual geometrical features. One isopropyl groups exhibits an expected eclipsed conformation with respect to the aromatic ring. The other isopropyl group shows a slight twist with respect to the aromatic ring. The short Cl⋯HC(methine) contact (2.88 Å) observed in the asymmetric unit is the probable reason for the twist feature around the isopropyl area.

5-Chloro-2-methoxy-anilinium nitrate.

Project description:The title salt, C(7)H(9)ClNO(+)·NO(3) (-), exhibits extensive hydrogen bonding between the ammonium functional group and the nitrate anion. A two-dimensional network of bifurcated N-H⋯O hydrogen bonds generates corrugated layers in the bc plane. The organic mol-ecules are stacked in a parallel orientation as a result of π-π inter-actions, with an inter-ring distance of 3.837 Å.

2-Carboxy-anilinium chloride monohydrate.

Project description:In the mol-ecule of the title compound, C(7)H(8)NO(2) (+)·Cl(-)·H(2)O, an intra-molecular N-H?O hydrogen bond results in the formation of a non-planar six-membered ring adopting a flattened boat conformation. In the crystal structure, inter-molecular O-H?O and N-H?Cl hydrogen bonds link the mol-ecules. There is a C=O?? contact between the carbonyl unit and the centroid of the benzene ring. There is a C=O?? contact [C?Cg = 3.5802?(18), C-O?Cg = 89?(1)°] between the carbonyl unit and the centroid of the benzene ring.

4-Eth-oxy-anilinium chloride.

Project description:The title compound, C(8)H(12)NO(+)·Cl(-), consists of an almost planar protonated 4-eth-oxy-anilinium cation with the N atom showing the biggest deviation from the plane formed by all non-H atoms of the cation [0.066?(1)?Å]. In the crystal, N-H?Cl hydrogen bonds link cations and anions into chains along the a axis. Additional C-H?? and ?-? inter-actions [centroid-centroid distance = 4.873?(2)?Å] stabilize the crystal structure.

2,5-Dichloro-anilinium chloride monohydrate.

Project description:The title compound, C(6)H(6)Cl(2)N(+)·Cl(-)·H(2)O, is composed of discrete cations, choride anions and water mol-ecules, which are connected through N-H?Cl, O-H?Cl and N-H?O hydrogen bonding. Two H atoms of the positively charged -NH(3) (+) group have two chloride acceptors and the other one has the O atom of the water mol-ecule as acceptor. The chloride anions form hydrogen bonds with two H atoms from two different water mol-ecules and two H atoms from two positively charged -NH(3) (+) groups.

3,4-Dimethyl-anilinium chloride monohydrate.

Project description:The crystal structure of the title compound, C(8)H(12)N(+)·Cl(-)·H(2)O, consists of hydro-phobic layers of dimethyl-anilinium cations parallel to the bc plane alternated by hydro-philic layers of chloride anions and water mol-ecules. The layers are linked by N-H?O and N-H?Cl hydrogen bonds involving the ammonium groups of the cations. The cohesion of the ionic structure is further stabilized by O-H?Cl hydrogen-bonding inter-actions.
